Yes Harry, these were mostly made at Fulper Pottery in Flemington NJ, the best I can tell there are 6 distinct script designs based on the way certain letters were done, the differences can be distinguished in the way the P in Paterson is done or by the N.J.. I don't know if there are any records to be found from Fulper to try and distinguish the name of the people who may have done the script work, but I'm going to look into it...
